The acetylcysteine is a drug belonging to the group of medicines called mucolytics and, usually sold in powder or effervescent tablets for oral solution. Below we will clearly expose the information that we must take into account when using this medicine.

Uses and action of acetylcysteine

Among the indications for this drug we find various conditions that affect the respiratory tract, particularly those that lead the human body to excessive secretion of thick mucus ( sinusitis , rhinopharyngitis or bronchitis among many others). Acetylcysteine ​​is responsible for fluidizing and facilitating the elimination and expulsion of mucus, so we can say that its main function is to reduce the viscosity of the patient’s mucus .


The consumption of acetylcysteine ​​is generally administered in doses of 600mg daily in adults and 300mg for children up to 12 years, administering the patient the daily dose either in a single dose (600mg every 24 hours) or in 3 doses of 200mg (one each 8 hours) according to medical prescription. Acetylcysteine ​​treatment usually lasts between 5 and 10 days depending on the severity of the condition and the viscosity of the mucus to be removed. Likewise, the patient is recommended to drink plenty of fluids for the duration of treatment with this drug , as it may be beneficial for mucus thinning.

Possible side effects of acetylcysteine

As with all medicines, acetylcysteine ​​may not have the desired effect on the patient or the patient may experience some side effects during treatment with the drug. Some of these adverse effects that may appear in the patient are nausea, vomiting, drowsiness, diarrhea, ringing in the ears, headache, skin rash or pain and heartburn . In the event that the patient suffers any of these effects, he should consult his doctor as soon as possible, who may decide to suspend the treatment. However, the probability that the patient suffers any of the adverse effects mentioned above is relatively low.(less than 1 in 1000 patients according to estimates). Nor should acetylcysteine ​​be administered together with antitussives and bronchial secretion inhibitors (antihistamines, anticholinergics …).

Why use acetylcysteine?

The use of this medicine can be very useful as long as we take into account all the aforementioned in terms of dosage, adverse effects, etc. Acetylcysteine ​​is a low-risk drug, easy to use and with generally positive results in a short period of time. Complications caused by excessive and viscous mucus that we cannot expel can pose a risk to our health in addition to generating great discomfort and discomfort in the patient, so it is important that we help to thin the mucus to facilitate its expulsion and thus avoid such risks and annoyances.

In any case (and even if it is a drug that is easy and simple to use), we must never forget that we are talking about a drug and that its use must always be responsible .It is always recommended that the patient carefully read the package leaflet of the drug when purchasing it, as there you will find all the information related to the product, in addition to the fact that it is possible that, as with most drugs, the excipients added to acetylcysteine ​​by different laboratories vary, and in some cases may affect the patient if he suffers some type of intolerance (for example lactose) or if he follows some type of special diet (also by way of example it is worth mentioning that in some acetylcysteine ​​leaflets we can find allusions to a high sodium content, advising people on low sodium diets to consult their doctor before starting treatment).
